Referring to fig. 1, 2 and 3, an embodiment of the present application provides a driving mechanism 10, which is applied to a cleaning device 100, wherein the driving mechanism 10 includes a driving member 11 and a lifting assembly 12, the driving member 11 has at least two output shafts, and the lifting assembly 12 is used for being connected with a cleaning assembly 30 for performing a cleaning operation in the cleaning device 100. At least one output shaft is used for being in driving connection with the cleaning assembly 30, and at least another output shaft is in driving connection with the lifting assembly 12, so that the cleaning assembly 30 is driven to perform lifting movement relative to the main body 20 of the cleaning device 100 through the lifting assembly 12.

It should be noted that the cleaning device 100 provided by the present application may be, but not limited to, a sweeper, a scrubber or other cleaning device 100 for cleaning the floor. For ease of understanding, a sweeper will be described below as an example.

The cleaning device 100 comprises a cleaning assembly 30, the cleaning assembly 30 being the structure of the cleaning device 100 that actually performs the cleaning operation, such as a roller mop 31. First, the driving mechanism 10 is provided on the main body 20 of the cleaning apparatus 100, and the lifting unit 12 in the driving mechanism 10 is connected to the cleaning unit 30.

The driving member 11 extends out of at least two output shafts, one of which is in driving connection with the cleaning assembly 30 and the other of which is in driving connection with the lifting assembly 12. Thus, the driving tool 11 drives the cleaning unit 30 and the elevating unit 12 via the respective output shafts.

The output shaft in driving connection with the cleaning assembly 30 is in particular in driving connection with the roller mop 31, so that the roller mop 31 is driven to rotate axially around itself, and the roller mop 31 can perform cleaning operations on the floor or other surfaces to be cleaned during rotation.

An output shaft in driving connection with the lifting assembly 12 can drive the lifting assembly 12 to do lifting motion relative to the main body 20, and meanwhile, the lifting assembly 12 drives the cleaning assembly 30 connected with the lifting assembly to do synchronous motion, so that the purpose of lifting the cleaning assembly 30 relative to the main body 20 is achieved.

The drum mops 31 are lifted while the cleaning assembly 30 is lifted up and down with respect to the main body 20, so that the drum mops 31 can be adapted to different height positions on the floor, and the cleaning apparatus 100 can be used more smoothly.

Through the above structure, at least two output shafts of the driving member 11 can be respectively connected with the cleaning assembly 30 and the lifting assembly 12 in a driving manner, the output shaft connected with the cleaning assembly 30 can drive the cleaning assembly 30 to perform cleaning operation on the surface to be cleaned, and meanwhile, the output shaft connected with the lifting assembly 12 can drive the lifting assembly 12 to move, so that the cleaning assembly 30 is driven to perform lifting motion relative to the main body 20 of the cleaning device 100 through the lifting assembly 12. Therefore, the driving member 11 can drive the cleaning assembly 30 and the lifting assembly 12 simultaneously, thereby cleaning and lifting the cleaning assembly 30, simplifying the overall structure of the driving mechanism 10, reducing the overall structure of the cleaning device 100, and facilitating operation and use.

As shown in fig. 4 and 5, in some embodiments, the driving member 11 includes a motor 13 and a gear assembly 14, the motor 13 includes a driving shaft (not shown), a first output shaft 131, and a second output shaft 132, the first output shaft 131 is configured to be in driving connection with the cleaning assembly 30, and the second output shaft 132 is configured to be in driving connection with the lifting assembly 12. The gear assembly 14 includes a first gear 141, a second gear 142, a third gear 143, and a fourth gear 144. The first gear 141 is in driving connection with the driving shaft, the third gear 143 is connected with the first output shaft 131, the fourth gear 144 is connected with the second output shaft 132, and the second gear 142 is meshed with the first gear 141, the third gear 143 and the fourth gear 144, and drives the first output shaft 131 and the second output shaft 132 to rotate.

Specifically, the first gear 141 is disposed on a driving shaft of the motor 13, and when the motor 13 is turned on, the driving shaft rotates around its own axis, thereby driving the first gear 141 to rotate synchronously. The third gear 143 is disposed on the first output shaft 131, the fourth gear 144 is disposed on the second output shaft 132, and the second gear 142 is meshed with the first gear 141, the third gear 143, and the fourth gear 144, respectively. Therefore, when the first gear 141 rotates along with the driving shaft, the first gear 141 drives the second gear 142 engaged with the first gear 141 to rotate synchronously, and then drives the third gear 143 and the fourth gear 144 to rotate synchronously through the second gear 142.

Through the above structure, the motor 13 can drive the plurality of gears to rotate simultaneously, thereby driving the first output shaft 131 and the second output shaft 132 to rotate.

The engagement connection between the first gear 141 and the second gear 142 may be a direct connection or an indirect connection via gears. The meshing connection between the second gear 142 and the third gear 143 and the fourth gear 144 may be direct connection or indirect connection via gears.

The first output shafts 131 are in driving connection with the roller mops 31 in the cleaning assembly 30, wherein one or more roller mops 31 can be provided, and the first output shafts are connected with the roller mops 31 in a one-to-one correspondence manner, i.e. each first output shaft 131 can drive one roller mop 31 connected with the first output shaft to rotate.

The second output shaft 132 is in driving connection with the lifting assembly 12, and the second output shaft 132 can drive the lifting assembly 12 to move in the rotation process, so that the lifting assembly 12 drives each roller mop 31 to perform lifting motion relative to the main body 20.

Further, in order to realize smooth connection between the motor 13 and the gear assembly 14, the gear assembly 14 may further include more gears, the gears may be in transmission connection through mutual engagement, and the specific number of the gears may be adjusted according to actual needs, so that each gear may be smoothly driven, and the first gear 141 on the driving shaft drives the third gear 143 and the fourth gear 144 to synchronously rotate, and finally drives the first output shaft 131 and the second output shaft 132 to rotate, which is not described herein.

In addition, the first gear 141 is connected to the driving shaft of the motor 13, and the first gear 141 may be formed of a metal material, such as copper or other metal materials. The second gear 142, the third gear 143, the fourth gear 144, and other gears in the gear assembly 14 may be made of POM plastic material to achieve weight reduction.

Referring to fig. 1 and 3 again, in some embodiments, the second output shaft 132 is provided with a one-way bearing 15, and the one-way bearing 15 is used to keep the lifting assembly 12 stationary when the motor 13 rotates forward, and to drive the lifting assembly 12 to move up and down relative to the main body 20 when the motor 13 rotates backward.

Specifically, the second output shaft 132 is drivingly connected to the lifting assembly 12, and a one-way bearing 15 is provided between the second output shaft 132 and the lifting assembly 12, so that the second output shaft 132 can be kept stationary when the motor 13 is rotated forward, thereby keeping the lifting assembly 12 connected to the second output shaft 132 stationary. At the same time, the first output shaft 131 rotates normally, and the first output shaft 131 drives each roller mop 31 connected with the first output shaft to rotate, so that each roller mop 31 can clean the floor smoothly.

When the motor 13 is reversed, the second output shaft 132 rotates along with the driving shaft under the action of the unidirectional bearing 15, and the second output shaft 132 drives the lifting assembly 12 to move, so that the lifting assembly 12 can drive each roller mop 31 to lift relative to the main body 20, and at the moment, each roller mop 31 moves upwards, so that the cleaning machine can adapt to the uneven area on the ground and can clean the ground better.

Referring to fig. 2 and 6 together, the present application also provides a cleaning device 100, which includes a main body 20, a cleaning assembly 30 and a driving mechanism 10, based on the same concept as the driving mechanism 10. The cleaning assembly 30 is disposed on the main body 20, at least one output shaft of the driving mechanism 10 is in driving connection with the cleaning assembly 30, and the lifting assembly 12 is connected with the cleaning assembly 30 and is used for driving the cleaning assembly 30 to perform lifting motion relative to the main body 20.

Specifically, the first output shaft 131 in the driving mechanism 10 is in driving connection with the cleaning assembly 30, wherein when the cleaning assembly 30 includes a plurality of roller mops 31, the first output shaft 131 may be provided in plurality and in driving connection with each roller mop 31 one by one.

A second output shaft 132 of the drive mechanism 10 is drivingly connected to the lifting assembly 12, and the lifting assembly 12 is connected to each roller mop 31. Thereby, the lifting assembly 12 is driven to move through the second output shaft 132, so that each roller mop 31 is driven to do lifting motion relative to the main body 20, and lifting of each roller mop 31 is achieved.

In some embodiments, the cleaning assembly 30 comprises a roller mop 31 drivingly connected to at least one output shaft, the roller mop 31 having a cleaning position and a raised position upon actuation of the lifting assembly 12. When the roller mop 31 is in the cleaning position, the roller mop 31 is used to perform a cleaning operation on a surface to be cleaned. When the roller mop 31 is in the raised position, the roller mop 31 is spaced from the surface to be cleaned.

Specifically, the first output shaft 131 is in driving connection with the roller mop 31, and the second output shaft 132 is in driving connection with the lifting assembly 12. In use, when the cleaning device 100 is cleaning a floor, the cleaning device 100 is placed on the floor. When the motor 13 rotates positively, the driving shaft drives the first output shaft 131 to rotate, and the first output shaft 131 drives the roller mop 31 to rotate, and at this time, the roller mop 31 contacts the ground and cleans the ground by rotating.

When the control motor 13 is switched from forward rotation to reverse rotation, the second output shaft 132 is driven by the driving shaft to rotate, so as to drive the lifting assembly 12 to move, and the lifting assembly 12 drives the roller mop 31 to gradually lift in the moving process, so that the roller mop 31 can avoid objects on the ground or can adapt to uneven ground.

In some embodiments, the cleaning device 100 further comprises a sensing member 40 provided on the main body 20, the sensing member 40 being used to sense the position of the roller mop 31 and to close the driving mechanism 10 when the roller mop 31 is moved to the raised position.

Specifically, the cleaning position is specifically the lowest point position of the roller mop 31, and the lifting position is the highest point position of the roller mop 31. The sensing member 40 senses the moving position of the roller mop 31, and when the roller mop 31 moves to the lifting position, i.e., the roller mop 31 moves to the highest point, the sensing member 40 controls the driving mechanism 10 to be turned off, and at this time, the lifting assembly 12 stops moving to stop lifting the roller mop 31. At the same time, the drum mop 31 also stops rotating. That is, when the roller mop 31 is moved to the raised position, the roller mop 31 is in a stopped state.

When the cleaning device 100 needs to be reused, the motor 13 can be turned on again and the motor 13 can be controlled to rotate forward, at this time, the second output shaft 132 is kept stationary under the action of the unidirectional bearing 15, the roller mop 31 descends to contact with the floor under the action of its own weight, and the roller mop 31 rotates under the drive of the first output shaft 131, so that the floor is cleaned.

In some embodiments, sensing element 40 comprises a photoelectric switch disposed on body 20. The photoelectric switch is arranged at a position corresponding to the lifting position of the roller mop 31, so that when the roller mop 31 moves to the lifting position, the photoelectric switch can smoothly sense the roller mop 31, thereby controlling the motor 13 to be closed, and the roller mop 31 can be stopped at the lifting position.

In some embodiments, the roller mops 31 comprise at least two, each roller mop 31 being connected to each output shaft in a one-to-one correspondence.

Specifically, there are two roller mops 31, a front roller mop 31 and a rear roller mop 31, respectively. Correspondingly, two first output shafts 131 are provided, wherein one first output shaft 131 is in driving connection with the front drum mop 31, and the other first output shaft 131 is in driving connection with the rear drum mop 31.

The two first output shafts 131 are provided with third gears 143, and when the motor 13 is started, the first gears 141 rotate along with the driving shaft, so that the second gears 142 meshed with the first gears are driven to synchronously rotate, and the two first output shafts 131 are driven to synchronously rotate, so that the front roller mop 31 and the rear roller mop 31 can synchronously rotate.

In some embodiments, the axial directions of the roller mops 31 are arranged parallel to each other, and the bottom surfaces of all the roller mops 31 together constitute a cleaning surface for performing a cleaning operation.

Specifically, the axes of the front roller mops 31 and the rear roller mops 31 are parallel to each other and are all disposed parallel to the horizontal plane, so that the bottom surfaces of the front roller mops 31 and the rear roller mops 31 together constitute a cleaning surface.

When the cleaning operation is performed, the cleaning surface is in contact with the floor, and rolling friction is formed between the cleaning surface and the floor by the rotation of the front roller mop 31 and the rear roller mop 31 around the axial direction of the front roller mop 31 and the rear roller mop, so that dirt on the floor is removed under the action of the rolling friction.

In some embodiments, the cleaning device 100 includes a sweeper.

In accordance with one or more embodiments, in the initial state, each roller mop 31 is in the cleaning position, i.e. each roller mop 31 is in contact with the floor. At this time, the motor 13 is turned on and the motor 13 is rotated in the normal direction, and the second output shaft 132 is kept stationary by the one-way bearing 15, so that the lifting assembly 12 is kept stationary. At the same time, the first output shaft 131 is driven by the motor 13 to rotate, so that each roller mop 31 is driven to rotate, rolling friction is formed between the cleaning surface of each roller mop 31 and the ground, and dirt on the ground is removed.

When the motor 13 is reversed, the second output shaft 132 rotates under the action of the one-way bearing 15, thereby driving the lifting assembly 12 to move. Specifically, the lifting assembly 12 may be configured as a lifting link, and a protrusion is disposed on the lifting link, and when the lifting link is driven by the second output shaft 132 to rotate around the self axis, the protrusion abuts against the main body 20 along the radial direction of the lifting link, so as to prop up the lifting link. Thereby, the lifting link drives each roller mop 31 connected thereto to lift.

When each roller mop 31 is lifted to the lifting position, namely, when each roller mop 31 is lifted to the highest point, the photoelectric switch controls the motor 13 to be turned off, and at the moment, the lifting assembly 12 stops moving, and each roller mop 31 stops lifting. At the same time, each roller mop 31 stops rotating, and remains stopped.

When the cleaning device 100 is reused, the motor 13 is turned on and the motor 13 rotates in the forward direction, and the lifting assembly 12 is kept stationary by the unidirectional bearing 15. At this time, the first output shaft 131 drives each roller mop 31 to rotate, and each roller mop 31 descends to contact the floor under its own weight, thereby cleaning the floor.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
